I'm just wondering if Duos will be in at launch and if you're planning on doing any sort of ranking system or after death spectate camera of your teammate at some point. Friend-o and I are mainly into duos in KOTK (and some rocket league) and besides all the bugs and hit reg problems we mainly just want more duos friendly features, like a spectate camera and a rank to improve or something. Maybe some sort of in depth stats or something could suffice. A lot of groups of friends in the KOTK subreddit are constantly asking for these things.

I don't know if duos will be a thing during the alpha launch, but yeah it will be a thing when the game comes out. Most of your questions, including about ranks, are actually answered in the trailer for this game.
